dcarrter21 Posted November 24, 2009 Share Posted November 24, 2009 ive recently had my exhuast sorted as i had a few issues with it...anyway. when they put it back together they used silicone sealant???? i was slightly puzzled but let them carry on as they do them everyday... everything seemed fine then i turned the boost up to 1.2 again. ive started getting a burning smell...like plasticy smell. what kinda temps would the 1st decat expect to get to? i think its just burning the silicone but just wanna check! cheers for reading!!!

Homer Posted November 24, 2009 Share Posted November 24, 2009 Silicon sealant on the exhaust?! It'll just melt... and stink, then leak. Who were these cowboys? Are you sure you heard them correctly, no sane mechanic would use silicon on an exhaust joint. Quote Link to comment Share on other sites More sharing options...
Jake Posted November 24, 2009 Share Posted November 24, 2009 Some proper exhaust sealant comes in gun-able cartridges just like silicone sealant does. I doubt they actually used silicone. Quote Link to comment Share on other sites More sharing options...
dcarrter21 Posted November 24, 2009 Author Share Posted November 24, 2009 it was silicone, im 100% sure,was clear when they put it on. i looked under the car the other nite and it looks like its seaping out of the flanges...it was flakey and looks like its being blown down the car onto other bits of the system.

dcarrter21 Posted November 24, 2009 Author Share Posted November 24, 2009 i cant think what else would be making that smell under the car? its definatly not coming from the engine bay... what temps would the 1st decat get on 1.2bar? 800deg?

Abz Posted November 24, 2009 Share Posted November 24, 2009 They might be using the same silicone as Jordon's boobies What sort of repair did they do? When you say you had a few issues & they had to put it together? I'd take it back to them as soon as possible, don't tell them you cranked the turbo up or they will blame that!

dcarrter21 Posted November 24, 2009 Author Share Posted November 24, 2009 i made a custom system myself and they basicly tidied the welding up for me.they took the whole lot off done the welding then put it back on with this 'sealant' Quote Link to comment Share on other sites More sharing options...
Homer Posted November 24, 2009 Share Posted November 24, 2009 Is the stuff seeping out clear or in white 'globs'? If they've used silicon it's a bodge, They should be using metal gaskets or at the very least firegum or similar exhuast paste. Is there any sign of exhaust gases blowing out from the joints?

dcarrter21 Posted November 24, 2009 Author Share Posted November 24, 2009 the stuff coming out is white but they defitnatly put on clear stuff. whatever it is its definatly splattered on the exhuast further down. its just bugging me what it is, ive got a dyno day on sat!!!! typical!
